The Lowdown
Alright, Rusty here. Let's take a good, hard look at what Kennebunk Beach has cookin' for us over the next couple of weeks.
Honestly, it’s a bit of a flat spell, folks. We’ve got a solid stretch of days with next to nothing on offer. From now until Thursday the 10th of September, don't get your hopes up. There’s really only one moment that even gets a pulse, and that’s Thursday afternoon, September 10th.
The water temp at Kennebunk Beach is sitting at 65°, which is a touch warmer than normal for this time of year – a little treat if you're paddling out.
So, the only real standout comes up on Thursday the 10th, in the afternoon. We’ve got some chest-high energy rolling in at 6ft, coming out of the East with a period of 7 seconds, and a combined swell energy of 319 – that’s the strongest pulse we see in the whole window. The wind will be light from the NNW, keeping things clean and cross-offshore. It’s not a perfect, long-period groundswell, but given the drought we’ve been in, this is the only window that’s even worth looking at. The swell direction is East, which is fine for this sheltered spot, but the optimum is ENE, so it’s a bit off.
Before that, the rest is all poor. We get a bit of a pulse on the 5th and 6th, but the wind is strong and messy, and the wave heights are just too small to get excited about. After the 10th, we drop right back into tiny, weak, and choppy conditions with wave heights barely hitting 2ft.
This is a tough run. Keep your eyes on that Thursday the 10th afternoon window, but don’t be surprised if it’s a bit ordinary. Forecasts can change, but right now, we’re in a dry spell.
Stay loose,
Rusty

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
